National Cycle VStream Low Windshield For Harley-Davidson - Details

National Cycle's VStream Windshields have turned the motorcycle windscreen world upside down - literally! National Cycle's innovative VStream Windshield gets its name from the unique shape and dimensional contours designed and engineered into the windscreen. The unique inverted "V" profile creates a quiet and comfortable riding experience unequaled by any windscreen on the market.

The typical airflow pattern of the wake from most windscreens is called a van Karman vortex. At speeds of 50-90 mph, the air swirls off the windscreen in an approximate 90-degree segment of rotation, hits the bottom of the rider's neck on the way up, and curves off the shoulder at approximately 45 degrees.

While other manufacturers offer taller screens or air spoiler tops, National Cycle designed a windscreen with airflow calculated and adjusted to quiet and comfort the rider's environment. The patented "V" shape is so quiet because it pushes this vortex out and away from the side of the rider's head, producing a quieter and more comfortable riding experience for both the rider and the passenger.
